“To develop the new publication, we conducted multi-year research trials, read piles of research papers, grew hundreds of plants for the photography sessions and spent hours working with editors and designers,” Abendroth said. One of the first steps was to conduct biomass and nutrient accumulation research, followed by four years of various research trials to fine-tune recommendations and facts in the book, and a year of growing plants for the publication images.

Much of the framework that was successful in the previous versions, including numerous color images and graphics, and descriptive text, has been retained in the new book. “Corn Growth and Development” is more than twice as long as the original, featuring 50 full-color pages, and is based on a new generation of corn hybrids and production research.

The new publication weaves the newest scientific facts regarding corn growth and development throughout the pages in a way that is concise and easily applicable for people in production agriculture. Key features include:

• More than 90 images, including whole-plant images from emergence to maturity;

• Detailed descriptions of vegetative and reproductive development;

• New dry matter and nutrient (N, P and K) accumulations figures;

• Clarification of corn development staging methods;

• An expansive list of end notes with agronomic research references.

“Corn Growth and Development”can be ordered from the ISU Extension Online Store at www.extension.iastate.edu/store for $14 per copy. Publication images will soon be available to purchase and download from the same location.
